MAHLE Smartbike Systems has launched the lightest e-bike drive system on the market, weighing in at just 3.2 kilograms—including the battery with its new X20 model. The Stuttgart-based automotive supplier’s e-bike business segment has thus set a new industry benchmark for the power-to-weight ratio of e-bike drives. The X20 also has an aesthetic advantage, because it is concealed within the bike’s frame and hub. In addition, artificial intelligence delivers a customizable cycling experience that is perfectly tailored to the rider. The new drive system is available as of April 20, 2022.
“With the X20, we are starting a completely new chapter by combining weight advantage, aesthetics, and customization in an unprecedented drive solution,” said Jochen Sommer, head of MAHLE Smartbike Systems.
“The X20 gives riders the exact support they need as individuals, providing the ultimate cycling experience,” added Marco de la Serna, head of Strategy and Business Development at MAHLE Smartbike Systems.
The MAHLE X20’s motor weighs just 1.4 kilograms. It is perfectly tailored to the design of gravel bikes and urban e-bikes and can be disconnected from the system with just one click. The rear wheel can thus be easily removed without technical expertise or special tools. The hub motor delivers 23 newton meters directly to the wheel—a power output comparable with that of a mid-drive motor with 55 newton meters of torque.
In addition, the X20 has a sophisticated sensor package that measures acceleration, speed, torque, temperature, and pedaling rate. It also uses artificial intelligence to continuously adapt the drive to the person in the saddle. The X20 thus offers a perfectly tailored cycling experience—even when riders or training conditions change. Further impressive features of the drive system are its absolutely natural pedal feel, which is similar to that of a conventional high-performance sports bike, and the noise-free support it offers the user. Communication between cyclist and vehicle takes place via a modern HMI with haptic feedback.
The two available batteries, iX250 and iX350, deliver sufficient energy in any situation. They can be quickly charged using the MAHLE Active Charger—easily reaching 80 percent charge within one hour. If more cruising range is needed, an optional range extender can be added. The range extender almost doubles the cruising range, weighs just one kilogram, and is shaped like a water bottle, which can be attached to the frame. By means of a docking station, this additional battery can also be used as a power bank to charge a laptop or mobile phones while on the go.
